Question

Describe the characteristics of visible light, and explain the process by which the eye converts light energy into neural messages. Explain how the Young-Helmholtz theory helps us understand color vision.

Answer 1

Part 1)

The characteristic of Visible lights are-

First in the characteristics of the seen light are it's own intensity of light, propagation direction in which it flows, frequency or wavelength spectrum of the visible light and polarization of light.

1)cornea- focal point that changes per facilities

- the membrane that secured with poles and cones.

- cones packed within the pay attention of the membrane or fovea)l delicate to splendid light-weight and shading vision.

Eyes converts light enegry into neural messages by-

The information goes through level cells to bipolar and amacrine cells optic nerves cross to the optic chiasm and in following ways-

- An associate data goes to the essential visual area.

-Then mind forms information got from vision.

Part 2)

Youthful Helmotz/trichromoatic hypothesis has explained that how it processee. It is the cones within the membrane of the eyes square measure enacted by light-weight waves connected with blue, red and inexperienced.

- We tend to see hues are a mix of those hues.
